I have Bitaddress.org from 2 months ago, version 6.2 saved on a USB and about to put 28 BTC on a BIP38 encrypted wallet, is it SAFE? WILL IT BE BUGGY CAUSE THEY UPDATED IT TWICE SINCE THEN? What are the new updates for 6.6 that makes it better? Thanks . AND is there anything I need to confirm when I send the bitcoins through blockchain onto a paperwallet? How many fees do I have to send to get it to confirm?
